Answer:

Final volume after applying 880 mmHg pressure = 89.28

Explanation:

Initial volume (V 1)= 100 ml

Initial pressure (P1) =780 mm Hg = 780/780 = 1atm

Final pressure (P2)=880 mm Hg = 880/780 =1.12 atm

Final volume (V2)=?

We know that,

Applying Boyle's law,

P1 V1=P2 V2

1*100=1.12*V2

100=1.12*V2

100/1.12=V2

89.28=V2

V2=89.28 ml

Draw both major organic product(s) that are obtained when 4-chloro-2-methyltoluene is treated with sodium amide followed by trea

victus00 [196]

Answer:

I attached the answer as an image. I also drew in the two most acidic hydrogens.

Explanation:

This goes through the 'benzyne' intermediate, meaning it does an E2-looking reaction by expelling a leaving group (chloride) from the adjacent part of the ring using the amide as a strong base. The triple-bonded benzyne has absurd bond angle strain, and is vulnerable to a good nucleophile like an amide ion, and the resultant sp2 anion is then reprotonated by the acid. I didn't draw in the acid-base reaction in step one, or the spectator ion (sodium).

A box is pushed across the floor for a distance of 5 metters with a force of 50N in 5 seconds. a. how much work is done? b. what

Reptile [31]

Answer:

50W

Explanation:

The formula and is

W = F × s

(force x distance)

W= 50 N× 5 m =250 N m=250 J

Done in 5 seconds the power is

where

Rolls of foil are 304 mmmm wide and 0.014 mmmm thick. (The density of foil is 2.7 g/cm3g/cm3 .) What maximum length of foil can

ratelena [41]

Answer:

92.2 m

Explanation:

Given that:=

The breadth = 304 mm

Height = 0.014 mm

Let Length = x mm

Volume = $Length\times breadth\times height$

Thus,

Volume = $304\times 0.014\times x\ mm^3=4.256x\ mm^3$

Also, 1 mm³ = 0.001 cm³

So, volume = 0.004256 cm³

Given that density = 2.7 g/cm³

Mass = 1.06 kg = 1060 g

So,

$Volume=\frac{Mass}{Density}=\frac{1060}{2.7}\ cm^3=392.59\ cm^3$

So,

0.004256*x = 392.59

x = 92243.89 mm

Length of foil = 92243.89 mm = 92.2 m
